Muhammad Ali (January 17, 1942) is an American former professional boxer, philanthropist and social activist. Originally known as Cassius Clay he won six Kentucky Golden Gloves titles, two national Golden Gloves titles, an Amateur Athletic Union National Title, and the Light Heavyweight gold medal in the 1960 Summer Olympics in Rome. Ali changed his name after joining the Nation of Islam in 1964 and converted to Sunni Islam in 1975. In 1967, three years after Ali had won the World Heavyweight Championship, he refused to be conscripted into the U.S. military, based on his religious beliefs and opposition to the Vietnam War. Ali was arrested and found guilty on draft evasion charges; he was stripped of his boxing title, and his boxing license was suspended. He was not imprisoned, but did not fight while his appeal worked its way up to the U.S. Supreme Court, where it was eventually successful. Ali would go on to become the first and only three-time lineal World Heavyweight Champion. Ali was diagnosed with Parkinson's syndrome in 1984, a disease to which those subject to severe head trauma, such as boxers, are many times more susceptible than average. Despite the disability, he remains a beloved and active public figure. This photograph was taken in 1983. The heavyweight champion boxer Muhammad Ali weighing-in before a fight. Date not indicated.
